Is there not a lever on the lock if you remove the panel that you can slide left or right. IIRC in one direction works as open with the alarm etc. the other direction would be permanently closed. To reopen you have to climb over rear seats into boot to open it.Hope some one can help please. I can shut my tailgate but the lock will not engage and consequently I can't lock it. Has anyone encountered this problem and know how I can solve it. Clearly I can't leave anything in the vehicle. Thanks.
